To all 'whom it may concern: Be it known that I, FREDERICK- B. H1B- BARD, `a citizen of the United States, residin at Philadelphia, in the county of Philade phia,l State of Pennsylvania, have inn vented a new and 'useful Valve,'ofwhich the following is slt-specification.

My invention relates to. improvements in valves, and is especially applicableto bibs or faucets, but may obviously be applied to other devices. y.

The object is to provide a valve simple in construction, easily operated, that shall be selfseatingand self-grinding, that shall be fluid tig-ht' without requiring washer. v

Referring to trate merely by embodiment v of my invention Figure 1 is alongitudinal vertical `section the drawings, which illustakeu on the line 1,1, of Fig. 4, showing the valve closed.

Fig-.2 is a similar View :showing the valve open'. t.

Fig. 3 is a vertical cross-section on l1ne 3, 3 of Fig. 1. j

Fig. l1 is a plan view vwith thel up or hous-4 f ing removed..` Y

` n the .specific embodiment Villustrated by' way of example, the valve 7 is shown as circular-1n plan provid d with a flat and per- AV fectly smooth working side adapted 'to rest and to be moved forward and backward on the seat S of the body 'of the bib 19, by'

the lever 5') projecting into the recess 10 on the underside, thereo ,to open and close the outlet port 11. The inlet port 12 in com munir-.ation wit-l the source of fluid "suppl-y is always open tothe chamber 13 formed by the housing or cap 111 surmountinp ".d

bodyll), so that the pressur, i tue fluid,

, either liquid ,or 33..., within the housing 1K1 -7, when the same is 1n the usual way of' example a 4suitableon the top of the valve the closed position.

is always exerted This pressure serves fluid tight. The periphery of the valve member 7 is provided with diagonally 'arranged grooves 15, so that the fluid, issuing fromthe port 12 and impinging said 4grooved periphery as said Huid passes out of port 11, when `the valve Vis in the open position, will cause ,said valve member 7 to rotate about the head or ball 16, seated in the recessor socket 1 0. It

will be understood that when port 11 isv open the pressure above and belowv the `valve member 7 will be more nearly equalized andsaid member will be free to rotate in l.re-

sponse to the force of the fluidl impinging upon the said grooved periphery. This turning of the valve member upon itsvseat, with very light pressure', whenever port 11 is open, serves to cause points of contact between the valve member and its seat, so that said valve member becomes self-grinding and self-adjusting, with the result that a fluid tight ]oint 1s maintained indefinitely. The greater' the pressure above the valve4 member 47' the tighter becomes the joint.

The coacting parts may be made of sufficient weight or thickness to permit of practically indeinite wear, The lever- 9 is shown as through' a suitable bushing connected with the handle 20.

- The special tapered or fiaringiinclined formation of the grooves is especially'advantageous in coperating with the stream port, a ilatyalve Seat surrounding the port,

a sliding. valve plumber,

to maintainasaid valvev an equal wear .at Aallprojerzjting 18-in the body -19 o1 the faucet or bib and its outerend` alle 1 having aA discharge l f I echanical means for awctuatingthe same to open andrlose the 'f discharge port, and means whereby the passage of iuid through the discharge causes aV rotative movement of said .valve member.

2. A chambered body having a por-t and a flat valve seat surrounding the port7 a sliding valve therefor and means whereby the ilnid passing through the port causes a rotative movement of the valve.

3. A ehambered body having' a port and a fiat valve seat surrounding the port, a sliding valve therefor having peripheral grooves as means whereby the valve is given a rotative movement on its seat. by the passage of the fluid. 4.

4. A chambered body havingT an intake and a discharge port and a flat valve seat surrounding the discharge port, ,1 flat valve slidable on said seat having peripheral grooves as means for antoniaticallyrotating the valve member as it is moved to uncover the port.

5. A chambered body having a discharge port and a flat valve seat surrounding the port, avalve member slidable on the seat to open and close the port, said valve member of such formation that. when actuated to nncover the port it is given a rotative movement by the action of the finid thereon.

6. A chambered body having a discharge port `nd a flat valve seat surrounding said port, a flat valve member slidable on the seat to open and close the port, a hand lever for causing the sliding movement7 and mea-ns for automatically causing a rotative movement of the valve member when actuated by the hand lever- 7. A chambered body having a port and a flat valve seat, a Hat valve member adapted to lie loosely by force of gravity and the pressure -of the Huid upon said seat, mechanical means for moving the valve member forward and backward upon .its scat and means for automatically causing a rotative movement of same when so actuated.

8. A chambered body'having a port and a liat'valve seat surr'onndmir the ort a valve member adapted to lie loosely` by force ofv gravity upon its seat, and` means t'or moving the valve member forward and backward and'also rotatively, including "a rockinglever having a ball and socket connection therewith.

9. A chambe-red body having a port and a flat valve scat surrounding the port, a valve memberadaptcd to lie loosely by force, of gravity' upon its seat, and means for moving the valve member i'orvim-rd and backward and also rotatively, including a rockingv leer .having a Aball and socket 'connection .`;lherewith which also forms a pivot bearing 'for its rotative movement.

10. A chambered body having a portand a I'fiat' valve seat surrounding the port, a valve member adapted to lie loosely by force of gravity uponits seat, and means for movingl the valve member forward and backward and also rotatively, including arrocking lever having a ball and socket connection therewith, which also forms a pivot bearing for its rotative movement, said valve member having suitably arranged peripheral grooves for coperation with the impinging fluid for causing its rotation.

11.. A chambered body having a port and a. flat valve seat surrounding the port, a valve member adapted to lie, loosely by'force of gravity upon its seat, and means for moving the valve member forward and back- -of the valve for actuating the same to open and close the discharge port, and means whereby the passage of fiuid from said inlet to the discharge causes a rotative move ment of said valve member.

13. A ehambered body provided with. inlet and discharge ports and a vfiat valve seatI surrounding one of said ports, a sliding valve member, ball and socket means `tor operating said member to open and close the port surrounded by the seat, the inlet so directed as to cause the fiuid'to How tangentially to the valve member to cause its rotative movement.

1,4. A ehambered body provided with inlet and discharge ports and a iat valve seat surrounding one ofv said ports, a sliding valve member, ball and socket means for operating said-member to open and close the port surrounded bythe seat, the inlet so direct-ed as to cause the fluid to flow in an upwardly inclined direction andsubstantially at a tangent to the valve periphery to canse a rotative movement of the valve.

'15. A chambered body provided with a discharge port and a .fiat valve seat sur' rounding said port, a sliding valve member having peripheral grooves, means for oper ating said member tol open and close the.

port, the inlet so directed as to canse the tion and substantial nection withl the center of the valve member 10 as means for operatin same to open and close the port surroun ed by the seat, the ports arranged to cause a flow tangentially to said member to cause it to rotate on its balland socket connection when the valve 15 .is in open position.
